compass.ocean.tests.global_ocean.mesh.qu.QUMeshFromConfigStep

class compass.ocean.tests.global_ocean.mesh.qu.QUMeshFromConfigStep(test_case, name='base_mesh', subdir=None, cell_width=None)

A step for creating quasi-uniform meshes at a resolution given by a config option

__init__(test_case, name='base_mesh', subdir=None, cell_width=None)

Create a new step

Parameters:

• test_case (compass.testcase.TestCase) – The test case this step belongs to

• name (str, optional) – the name of the step

• subdir ({str, None}, optional) – the subdirectory for the step

• cell_width (float, optional) – The approximate cell width in km of the mesh if constant resolution

Methods

__init__(test_case[, name, subdir, cell_width])	Create a new step
add_input_file([filename, target, database, ...])	Add an input file to the step (but not necessarily to the MPAS model).
add_model_as_input()	make a link to the model executable and add it to the inputs
add_namelist_file(package, namelist[, ...])	Add a file with updates to namelist options to the step to be parsed when generating a complete namelist file if and when the step gets set up.
add_namelist_options(options[, out_name, mode])	Add the namelist replacements to be parsed when generating a namelist file if and when the step gets set up.
add_output_file(filename)	Add the output file that must be produced by this step and may be made available as an input to steps, perhaps in other test cases.
add_streams_file(package, streams[, ...])	Add a streams file to the step to be parsed when generating a complete streams file if and when the step gets set up.
build_cell_width_lat_lon()	A function for creating cell width array for this mesh on a regular latitude-longitude grid.
constrain_resources(available_resources)	Constrain cpus_per_task and ntasks based on the number of cores available to this step
make_jigsaw_mesh(lon, lat, cell_width)	Build the JIGSAW mesh.
process_inputs_and_outputs()	Process the inputs to and outputs from a step added with compass.Step.add_input_file() and compass.Step.add_output_file().
run()	Run this step of the test case
runtime_setup()	Update attributes of the step at runtime before calling the run() method.
save_and_plot_cell_width(lon, lat, cell_width)	Save the cell width field on a lon/lat grid to self.cell_width_filename and plot
set_resources([cpus_per_task, ...])	Update the resources for the subtask.
setup()	Set up the test case in the work directory, including downloading any dependencies.
update_namelist_at_runtime(options[, out_name])	Update an existing namelist file with additional options.
update_namelist_pio([out_name])	Modify the namelist so the number of PIO tasks and the stride between them consistent with the number of nodes and cores (one PIO task per node).
update_streams_at_runtime(package, streams, ...)	Update the streams files during the run phase of this step using the given template and replacements.
